Determine the phenotype for each genotype below. Label which phenotype will be ROUND and which will be POINTY.
In dogs, round shaped ears are dominant to pointy shaped ears.
RR=? Rr=? rr=?
RR= Round
Rr=Round
rr= Pointy

In pea plants, tall (T) is dominant to short (t). If two heterozygous tall pea plants are crossed, what is the probability that the offspring will have the tall phenotype? What is the probability that the offspring will have the short phenotype?
3/4 or 75%= TALL
1/4 or 25%= SHORT
A robin builds a next in a tree. What kind of symbiotic relationship is this?
Commensalism
Curly hair (H) is dominant to straight hair (h), and brown hair (B) is dominant to blonde hair (b). Two parents that are each heterozygous for both traits decide to have children. What would the phenotypic ratio of all their offspring be?
9/16= HB or Curly Hair, Brown Hair
3/16= Hb or Curly Hair, blonde hair
3/16= hB or Straight Hair, Brown Hair
1/16= hb or Straight Hair, blonde hair
In birds, a short beak (B) is dominant to a long beak (b) and strong wings (A) are dominant to weak wings (a). A bird that has homozygous long beak and homozygous strong wings is crossed with a bird that has homozygous short beak and heterozygous strong wings. List all possible phenotypes below.
100%= BA
100%= Short Beak, Strong Wings
Bees use a flower's nectar for food, and they carry a flower's pollen to other flowers, allowing for flowers to reproduce. What type of symbiotic relationship is this?
Mutualism
Two parents are wondering what their offsprings blood type will be. The mother has type O blood and the father has heterozygous type B blood. What are the possibilities of their offsprings blood type?
50% BI or Type B Blood
50% ii or Type O Blood
Dr. Smith is treating a young couple who are having a child. The parents are worried that since the mom is a carrier for the disorder of color blindness that the child will have color blindness as well. The father does not have color blindness. What are the chances that the child will NOT have color blindness?
Use XB for no color blindness and Xb for having color blindness.
75% chance NOT color blind
